The Knickerbocker is a sweetheart of a drink, dating back to at least 1850 according to The Washington Post. It has a simple, likable flavor akin to something like a melted Popsicle, but in the best possible way.
Shake all ingredients with ice. Strain into a small, chilled cocktail glass and garnish with a lime twist.
